There have been instances of bluebeam acting slowly or not reacting normally to user actions. Example: user dragging or placing lines and they don't end up where selected. 

The following site describes how to save Bluebeam settings and restoring if needed, as well as resetting the user's profile. 

In many cases, a profile reset within Bluebeam should resolve the issue(s).

Backing up, resetting & restoring your Revu preferences, tool sets & profiles

• Created 03 August 2020

Backing up your Revu settings

Backing up your Revu settings creates a .zip file that you can revert to in case you experience computer issues, or if you need to migrate to a new computer. Even if you’re not immediately moving to a new computer, it’s a good idea to keep a backup file in a location other than your local hard drive, so it can be restored in the event of a hard drive failure.

To back up your settings with Revu:

1. Open Revu .
2. Go to Revu > Preferences (Ctrl+K).
3. From the sidebar select Admin, then click Options at the top.
4. Click Backup.
5. When prompted, save your .zip file to a secure location.

Your back up Revu .zip file has been saved. Repeat this process as necessary, such as when you make significant changes to your setting.

Manually backing up your settings

You can also back up the entire folder manually, or add the folder to your backup routine. It’s located in:

C:\Users\<UserName>\AppData\Roaming\Bluebeam Software\Revu

Once you’re inside the Revu folder, you’ll see a sub-folder labeled 20 or 19 (named after the installed version).

Resetting your Revu settings

The reset settings option in Revu resets your settings to their original configurations. Before proceeding, it’s recommended to back up your settings in case this reset doesn’t produced the desired result.

To reset your settings:

1. Open Revu .
2. Go to Revu > Preferences (Ctrl+K).
3. From the sidebar select Admin, then click Options at the top.
4. Click Reset, then click OK.
   Revu will now close and re-launch on its own.

Your Revu settings have been reset to their original configurations.

Restoring your Revu settings

Restoring your settings lets you return your Revu configuration settings to a previous state by uploading a backup file.

To restore your settings:

1. Open Revu .
2. Go to Revu > Preferences (Ctrl+K).
3. From the sidebar select Admin, then click Options at the top.
4. Click Restore, then click OK.
5. Locate your Revu settings backup file and click Open.
   Revu will now close and re-launch on its own.

Your Revu settings have been restored.
